I just found this thread because of the nice comment on Venus Oil. Thanks, chaitanya.
Now, to get back to the Neptune / Poppy seeds query of February 12, 2011 -- YES, those are Poppy seeds and the use is absolutely deliberate.
Neptune is the planet that rules dreams and drugs, especially drugs that make you dream, and the most important of these is opium, which has a long history of use as a sacred drug (e.g. in ancient Crete) and also ABuse (see any street junkie).
Poppy is the plant from which most (but not all) opium is made. (It also exists in Lettuce, of all places). So Poppy seeds symbolize and put us in contact with the beautiful and medicinal and dream-inspiring aspects of the Poppy plant and opium -- and, yes, the negative aspects as well (addiction, befuddlement, confustion).
Let us consider this: every planet has positive and negative qualities. Some are mostly postivie (Jupiter and Venus come to mind). But even they have negative qualities (Jupiter becomes obese and also over-spends, Venus becioomes vain, lazy, and hyper-conscious of beauty).
Some planets are neutral (Mercury is a good example).
Some are fairly negative (Saturn and Mars are classically considered in this way).
Neptune has as many good qualities as negative, but the negative qualities are intimately tied to the good qualities: Dreaminess or narcosis? Psychicism or delusions? Imaginative visions or drug abuse? Each of these paired ideas relates to the other, and Neptune encompasses them all. Poppy seeds make a nice topping to challah bread. Poppy seeds are also the generative expression of the poppy plant that has ruined so many, many lives by wasting them in fruitless fantasies.
Yes, the choice of Poppy seeds was deliberate. Caveat emptor.
